The answer seems obvious at first glance:
Pos-shorts to work from home and when I paste it wins.
However, in practical considerations must take a lot deeper than that before deciding on a life of self-employed. The first thing you should consider is your current situation: Do you have a fabulous job I am satisfied not only financially but personally? Besides earning a well handled satisfactorily work with your superiors, your colleagues and office with your clients? Are you a Mexican Congressman occurring only once a month to collect their check? In these cases nor move.
Becoming a freelancer is like jumping into a vacuum without a parachute. In the best cases is like jumping into a vacuum with an umbrella and wrapped in polyurethane foam. In a word, is not safe.
Personally, I took 7 years to decide to make the leap. During that time I worked in the design of a large commercial printing, which in turn was a producer of notebooks and school supplies which in turn made and natural products which in turn had different boxes and packaging. I do not pay very well (actually I paid very badly), but it was a salary insurance. And during the first 4 years was spent very well and I felt that I was learning and getting ready for something better. Over the next 2 years my happiness was falling gradually to the point where they no longer stand up in the morning to go to work. Then I jumped.
There were difficult times during the first months of despair and I even missed until the safety of my old and boring work. However, when I realized the freedom we enjoy and that was all that effort it was investing in something in me and my doubt is cleared.
So back to the original question: Why do you want to get freelancer? Possible responses:
* Because your current situation does not fill you at all.
* Because you have control over your destiny.
* Because you want to build for yourself and not for someone else.
* Because I like challenges.
* Because this is not the time to try it in 5 or 20 years.
* Because you know you can.
